Sure, as an AI language model, I can help you with that.
In Ruby, there are several primitive data types. Here are some examples:
1. Integers: These represent whole numbers and can be positive, negative, or zero.
Example: 50, -10, 0
2. Floats: These represent decimal numbers.
Example: 3.14, -0.5, 9.0
3. Booleans: These represent true/false values.
Example: true, false
4. Strings: These represent text. They can be surrounded by single quotes (') or double quotes (").
Example: "hello", 'ruby', "123"
5. Symbols: These represent immutable values that are commonly used as keys in hashes.
Example: :name, :age, :address
Here is an example of a Ruby code that uses some of these primitive data types:
age = 25 # integer
height = 5.11 # float
is_male = true # boolean
name = "John" # string
city = :Austin # symbol
I hope that helps!
